Adding active search capabilities to the table component

[steve-manywho]

The table component could use the option for "active search" which basically means the user doesn't need to hit the search button. I've put in a listener that waits for the user to stop typing for 1 second before performing the search request to stop it from storming the underlying service with requests. You can test it out here (if you can login to our demo salesforce org):

@steve-manywho This would be better implemented in the onSearchChanged handler in table-container.js. We have a debounce function at manywho.utils.debounce that will call a function after a timeout where the timeout gets reset each time the function is attempted to be called.
